The ECG findings presented as normal in athletes were established by an international consensus panel of ... The QRS rate for junctional rhythms is typically less than 100 beats/min, and the QRS ...

Less commonly, SCD manifests without prior disease symptoms in individuals with structurally normal ... (flat ECG) between ventricular depolarization (reflected by the QRS complex) and ...

A normal ECG contains waves, intervals, segments and one complex, as defined below. Wave: A positive or negative deflection from baseline that indicates a specific electrical event. The waves on ...

This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless. For example, the normal QRS complex in lead V1 does not ...

The goal of ECG interpretation in athletes is to classify the ECG as: (1) ‘normal’—no further evaluation needed or (2) ‘abnormal’—further evaluation needed. Normal ECGs include common, ...

They are characterized by premature, wider-than-normal ... precede the next sinus complex; otherwise, sinus depolarization would suppress it 2,3. Figure 2: An ECG obtained from a beagle dog ...
